Another object'of the invention is to. provide `a mattress filling boxdesigned to contain the :mattress covering, or tick, to be filled and which is of such construction as to readily permit the passage of air there through and which is of such shape as to restrict the ends of the tick vertically and to allow the vertical expansion of the intermediate portion of the tick and thus produce a uniform crowned center, which mattress in use will pack uniformly from end to end.

More specifically an object of the invention is to provide a mattress filling box formed of upper and lower frames whose facing sides are arcuate from end to end and are formed of screening, such as wire mesh, so as to not obstruct the passage of air, the upper frame being hinged at one end and releasably secured, at its other end, in a fixed relation to the lower frame while the tick, or covering, is being filled with the cotton or other fibrous material; said frames being so shaped, as above described, to the end that the end zones of the covering will be restricted more than the intermediate zone so that when the cover is filled with brous material the mattress will have a uniform crowned center.

Another object of the invention is to provide a mattress filling box that may be readily opened for the insertion of the cover or for the removal of the mattress after it has been filled.

With the above and other objects in view the invention has particular relation to certain novel features of construction, arrangement of parts and use, an example of which is given in this specification and illustrated in the accompanying drawings herein:

iFigure 1 shows a side elevation, partly in sect on.

Figure 2 shows a plan view and Figure 3 shows a cross-sectional view taken on the line 3-3 of Figure 1.

Referring now more particularly to the drawings wherein like numerals of reference designate the same parts in each of the figures the numerals I and 2 designate, respectively, upper and lower skeleton frameworks which may be composed of any suitable material such as wood or metal.

The lower framework may be permanently located on a suitable support such as the floor 3..

to a mattress filling box.`

The upperframework is 'spaced above the lower framework and at its rear end is hinged to a suitable upright, such as the wall 4, by the' hingesi'i, 5. ,L

A cable E is attached'at oneend, to the forward end of the framewtrk l, and this cable works over theoverheadsheaves"I, 1 suspended from the overhead ceiling.v The other end of the cable 6 carries a counterweight 8. The upper framework is thereby counterbalanced and may be easily lifted and lowered.

The facing sides of the upper and lower framework are concaved or curved, from end to end as shown and said facing sides are composed of foraminated material such as wire mesh 9, Iii.

The mattress covering, or tick, II, formed of fabric is placed between the upper and lower trames preparatory to filling it with lint cotton or other fibrous material.

This fibrous material is conditioned by a suitable machine as I2 and delivered, under air pressure, through the wide chute I3 into the covering il. For this purpose the forward end of the covering is open and is clamped around the adjacent end of the chute I3 by means of a clamp I4.

While the tick is being lled the upper frame is held down by means of a releasable hook I5 which is connected, at one end, to the chute and whose other end engages through an eye IIS on the forward end of the upper frame.

The air entering the tick, or covering, II will inflate the latter and said air will pass on out through the fabric covering and out through the wire mesh 9, I0 with a minimum of obstruction. The lint cotton or other ber will be carried along in the air current and will be deposited first in the end of the tick, or covering, remote from the chute and said covering will be gradually lled from end to end. The ends of the mattress covering are contracted by the ends of the upper and lower frames, as shown in Figure 1, so that less fiber will be deposited in the ends than along the intermediate portions so that the mattress will be uniformly crowned on its upper and under sides and from end to end so that when the mattress is subjected to use its intermediate portion which sustains the main weight of the body of the sleeper will contain more of the filling material than the ends which are subjected to minor Y portions of the weight. Accordingly the mattress will in use eventually assume a substantial uniform vertical thickness from end to end.

When the covering I I has been completely filled the hook I5 may be disengaged and the forward sides of the frames being concaved from end to end, foraminated material covering thefacing sides of said frames, a fabric sack between the frames and of substantially the same length and width as the frames and formed of material that will allow the air to pass therethrough, an inlet chute of substantially the same width as the sack and entering one end of the sack and means for delivering a. lint-like filler through said chute and into said sack to ll the sack.
